PURPOSE:To prevent adherence of foods to the ceiling plate of the titled oven range by applying a fluororesin coat onto the surface of the ceiling plate made of iron or formed with an enameled film on the surface of an iron sheet or the like. CONSTITUTION:The surface of an iron-made ceiling plate 2 is coated with a fluororesin 5 such as polyterafluoroethylene and applied with a film, whereby, because of non-tackiness possessed by the fluororesin, adherence of foods to the ceiling plate 1 is prevented. The heat-resisting temperature of the fluororesin is about 200 deg.C, and the heater of the oven is disposed on the upper surface and the lower surface within the range and is separated from the ceiling plate. Therefore, in a state where foods are placed in the range, the temperature of the ceiling plate becomes 200 deg.C or less, and hence it gives rise no problem. However, it is desirable that the watt density of the heater is 5w/cm<2> or less. |
